1.11
RISK OF EXPLOSIVE GASES.
a.
WORKING IN VICINITY OF A LEAD-
ACID BATTERY IS DANGEROUS.
BATTERIES GENERATE EXPLO-
SIVE GASES DURING NORMAL
BATTERY OPERATION. FOR
THIS REASON, IT IS OF UTMOST
IMPORTANCE THAT YOU FOL-
LOW THE INSTRUCTIONS EACH
TIME YOU USE THE CHARGER.
b.
To reduce risk of battery explo-
sion, follow these instructions and
those published by battery manu-
facturer and manufacturer of any
equipment you intend to use in
vicinity of battery. Review caution-
ary markings on these products
and on engine.
2. PERSONAL SAFETY PRECAUTIONS
2.1
Consider having someone close
enough by to come to your aid when
you work near a lead-acid battery.
2.2
Have plenty of fresh water and soap
nearby in case battery acid contacts
skin, clothing, or eyes.
2.3
Wear complete eye protection and
clothing protection. Avoid touching
eyes while working near battery.
2.4
If battery acid contacts skin or cloth-
ing, wash immediately with soap and
water. If acid enters eye, immediately
flood eye with running cold water for
at least 10 minutes and get medical
attention immediately.
2.5
NEVER smoke or allow a spark or
flame in vicinity of battery or engine.
2.6
Be extra cautious, to reduce risk of
dropping a metal tool onto battery.
It might spark or short-circuit bat-
tery or other electrical part that may
cause explosion.
2.7
Remove personal metal items such
as rings, bracelets, necklaces, and
watches when working with a lead-
acid battery. A lead-acid battery can
Page 6
produce a short-circuit current high
enough to weld a ring or the like to
metal, causing a severe burn.
2.8
Use the charger for charging only
12V lead-acid or lithium ion LiFePO4
rechargeable batteries. It is not
intended to supply power to a low
voltage electrical system other than
in a starter-motor application. Do
not use battery charger for charging
dry-cell batteries that are commonly
used with home appliances. These
batteries may burst and cause injury
to persons and damage to property.
2.9
NEVER charge a frozen battery.
3. PREPARING TO CHARGE
3.1
If necessary to remove battery from
vehicle to charge, always remove
grounded terminal from battery first.
Make sure all accessories in the vehi-
cle are off, so as not to cause an arc.
3.2
Be sure area around battery is well
ventilated while battery is being
charged.
3.3
Clean battery terminals. Be careful to
keep corrosion from coming in con-
tact with eyes.
3.4
Add distilled water in each cell until
battery acid reaches level specified by
battery manufacturer. Do not overfill.
For a battery without removable cell
caps, such as valve regulated lead
acid batteries, carefully follow manu-
facturer’s recharging instructions.
3.5
Study all battery manufacturer’s spe-
cific precautions while charging and
recommended rates of charge.
3.6
Determine voltage of battery by
referring to car owner’s manual and
make sure that output voltage selec-
tor switch is set at correct voltage. If
charger has adjustable charge rate,
charge battery initially at lowest rate.
4. CHARGER LOCATION
4.1

back in.
CHARGE COMPLETION
AND MAINTAIN MODE
(FLOAT MODE MONITORING)
Charge completion is indicated by the
GREEN LED pulsing and the digital display
showing FULLY CHARGED AUTO MAIN-
TAINING. This means that the charger has
stopped charging and has switched to the
Maintain Mode of operation. NOTE: If the
charger has to provide its maximum main-
tain current for a continuous 12 hour period,
it will go into Abort Mode (see Aborted
Charge section). This is usually caused by
a drain on the battery, or the battery could
be bad. Make sure there are no loads on
the battery. If there are, remove them. If
there are none, have the battery checked
or replaced.
MAINTAINING A BATTERY
This unit maintains 12 volt batteries, keep-
ing them at full charge. It can charge small
batteries and maintain both small and large
batteries. If you are maintaining a fully
charged large battery, you are properly uti-
lizing the battery charger. However, if you
use this battery charger to charge a large
battery, such as a marine deep-cycle bat-
tery, that was not fully charged, you may
lose some of the battery’s capacity. There-
fore, we do not recommend charging a
large battery with this unit.
NOTE: The maintain mode technology
allows you to safely charge and maintain
a healthy battery for extended periods of
time. However, problems with the bat-
tery, electrical problems in the vehicle,
improper connections or other unantici-
pated conditions could cause excessive
current draws. As such, occasionally
monitoring your battery and the charging
process is required.
DESULFATION MODE
If the battery is left discharged for an
extended period of time, it could become
sulfated and not accept a normal charge.
If the charger detects a sulfated battery,
the charger will switch to a special mode
of operation designed for such batteries.
If successful, normal charging will resume
after the battery is desulfated. Desulfation
could take up to 8 hours. If desulfation fails,
charging will abort, the GREEN LED will
flash, and the display will show CHARGE
ABORTED-BAD BATTERY.
ABORTED CHARGE
If charging cannot be completed normally,
charging will abort. When charging aborts,
the charger’s output is shut off, the GREEN
LED will flash, and the display will show
CHARGE ABORTED-BAD BATTERY. Do
not continue attempting to charge this
battery. Check the battery and replace, if
necessary.
